&nbsp;the Ethereum network performed strongly in 2025, processing a record volume of transactions and dominating the DeFi market (mainnet TVL accounted for 64%). However, the ETH price fell 10% throughout the year to below $3,000, decoupling from network activity. Because Ethereum proactively reduced transaction fees through technical upgrades to promote the growth of L2 networks and the expansion of the entire ecosystem, mainnet revenue declined significantly. In 2025, total L2 revenue fell 53% to $129 million, but fees paid to the mainnet sharply dropped to only $10 million, with L2 operators retaining about $119 million in profit. This means the Ethereum mainnet “sacrificed” over $100 million in potential revenue (a decrease of about $103 million compared to 2024) to subsidize ecosystem growth.

U.S. Congressman Warren Davidson warns that the United States is sliding towards a licensed and tightly monitored financial system. He believes that the recently passed cryptocurrency legislation undermines the industry's original promise of permissionless private money. Warren Davidson posted on the X forum criticizing the stablecoin-focused GENIUS Act, stating that the bill will give rise to a wholesale version of the U.S. dollar central bank digital currency (CBDC), which could be used for "surveillance, coercion, and control." He also expressed concern that a digital identity system might be introduced in the future, forcing Americans to obtain government permission to use their own money.

According to Cointelegraph, a bug in the smart contract code for the Ethereum Alarm Clock service has been exploited, with nearly $260,000 said to have been swiped from the protocol so far. The Ethereum Alarm Clock enables users to schedule future transactions by pre-determining the receiver address, sent amount, and desired time of transaction. Users must have the required Ether on hand to complete the transaction and need to pay the gas fees upfront. According to an Oct. 19 Twitter post from blockchain security and data analytics firm PeckShield, hackers managed to exploit a loophole in the scheduled transaction process which allows them to make a profit on returned gas fees from canceled transactions. Web3 security frim Supremacy Inc also provided an update, pointing to Etherscan transaction history that showed the hacker(s) were so far able to swipe 204 ETH, worth roughly $259,800.
